 
This view is of fisheries biologists using electro-fishing equipment to sample the fish in the stream. The “shocker” temporarily stuns the fish so that they can be easily captured, measured and weighed, and then released into the stream. The stream is Little Stony Creek, a native brook trout stream in the Shenandoah Watershed, on the Lee Ranger District, George Washington and Jefferson National Forests. The fish populations in this stream are being monitored following a liming treatment that was done to combat the effects of acid deposition. The trout as well as other fish, are currently thriving in the stream. This sampling method was also used within the Shenandoah watershed to survey for the presence and abundance of American eels. The catadromous eels (spawn in the ocean, and live as adults in fresh-water) can be found all the way to the headwaters of many streams. They move inland from the ocean as juveniles, and then travel back to the ocean to spawn. The construction of dams on larger rivers has made it difficult for the eels to migrate to and from the sea.
